OPERATING MODEL


Scenario in General : Present & Likely future

PRESENT FUTURE

• Single plant up to 300 KLPD

• Reasonably low energy

consumption

• Sustainably reduced water

consumption

• Recovery of maximum by

products

• Relatively low pollution &

Damage to environment

• Proven Effluent treatment

packages for Grain & Molasses

distilleries

• Further enhanced capacities

• Refining & Purification of Co-

products & waste generated

from plant

• Maximization of value

through Value Added

Products

• Integrated Schemes &

Models with focus on ZERO

LIQUID DISCHARGE with

minimum energy

consumption.


Energy & water Scenario : Present & Likely future

PRESENT FUTURE

• Overall steam consumption in

grain plants 4.5 Kg/lit – 5.0

Kg/lit

• Unused waste energy

• 9-10 Lit/Lit fresh water

consumption

• Substantial Cooling water

requirement

• Steam consumption @ 4.0

kg/lit

• Waste / Recycle stream will

have same temperature as

input temperature

• Minimum cooling water

requirement

• Lowest possible Fresh Water ;

Consumption Limited to

Atmospheric losses only

OPERATING MODEL


General Concerns…….

• Lower Recoveries

• Higher steam consumption

• Inferior Product quality

• Higher Impure Spirit Cut

• Non utilization of 100 % syrup

• Evaporation of spent wash to the RIGHT SOLIDS

• Working of Spent wash incinerator

• Quality of DDGS

• How to approach ZERO LIQUID DISCHARGE?

• Process Streams

• Non Process streams

• Steam & Power Balance

TECHNICAL:

• Right Project Investments

• Ideal Operating Costs

• Commercial Viability of expansions

FINANCIAL:

• Skill sets of Team

• Operational philosophy

• Right mix between Manual Operations Vs Automation

OPERATIONAL


Challenges…..

Grain Based Plants

• Further reduction in energy consumption

• Evaporation of entire quantity of thin slops without steam

• No recycle of Thin slops in the Liquefaction

• Maintaining higher solids in thick slops

• Use of 100% Syrup in Drying process

• Use of Dryer vapours for energy optimization

Molasses Based Plants

Effluent treatment:

• BSW / RSW / RO Reject Evaporation

• Reduction in steam & energy

• Recycle of waste streams

Investment:

• Which route : EPC/EPCM/ Turn Key Contract ?

• In house Project Management or out sourced ?


Two different types of Feed

Wet cake + Thick Slurry

Variation in feed specifications

• Inlet solids

• Different grains as feed to Distillery

• Stable unit operations (Decantation & Evaporation)

Large amount of mass

Higher Steam Consumption

Capability to handle Syrup

Higher product temperature

Higher Back Mixing

Maintaining Nutritional value of DDGS

Maintaining DDGS Color & Fragrance

Challenges in Drying @ DDGS


DDGS Drying : Case Study

Higher starch Grains : Rice Lower Starch Grain : Corn, Bajara

• Plant Capacity : 100 KLPD Total Spirit

• Starch content : 68 %

• Alcohol concentration in FW : 14%

• Thick slop Generation : ~ 496 m3/Day

• Wet Cake Generation : ~ 100 Ton/Day

• Thin Slop Generation : ~ 396 m3/Day

• Solids in thin Slop : ~ 3.5 %

• Solids in Syrup : 35 % max.

• Qty. of DWGS : ~ 139.6 Ton / Day

• Plant Capacity : 100 KLPD Total Spirit

• Starch content : 60 %

• Alcohol concentration in FW : 13 %

• Thick slop Generation : ~ 549 m3/Day

• Wet Cake Generation : ~ 149 Ton/Day

• Thin Slop Generation : ~ 400 m3/Day

• Solids in thin Slop : ~ 6.5 %

• Solids in Syrup : 35 % max.

• Qty. of DWGS : ~ 223 Ton/Day

62% Increase in DDGS Dryer Capacity ???


What does it mean…

Dryer for which material?

• Usage pattern of RM on yearly basis

• Influencing Grain

• Uniform mix of usage

• Heavy use of one type of Grain on yearly basis

• Selection Criteria:

• Technical Requirement

• Investment Vs Returns

• keep option of DWGS !!!
